Can the legendary fog and haze really come back to life and cure all diseases? What principle?

In ancient times, it was often said that opium was opium. In fact, opium was first used as an analgesic for rheumatic bone pain because it can relieve pain. Naturally, it is not so serious, and resurrection is more complicated. This kind of resurrection does not mean that people are really dead, but a state of suspended animation, which may cause people's mental excitement after smoking opium, or stimulate people's potential to wake up from a deep coma or severe shock. In fact, the armies of all countries are equipped with drugs similar to morphine, and soldiers will be injected with a needle when they are dying.
